This paper presents the SCADE System™ product line for systems
modeling and generation based on the SysML standard and the Eclipse
Papyrus open source technology. SCADE System has been developed in
the framework of Listerel, a joint laboratory of Esterel
Technologies, provider of the SCADE® tools, and CEA LIST, project
leader of the Eclipse component, Papyrus.
From an architecture point of view, the Esterel SCADE tools are
built on top of the SCADE platform which includes both SCADE
Suite®, a model-based development environment dedicated to critical
software, and SCADE System enabling model-based system engineering.
SCADE System includes Papyrus, an open source component (under EPL
license), integrated in the modeling platform of Eclipse. Using
this integrated modeling platform, both system and software teams
share the same environment for system development. Furthermore,
other model-based tools can be added to the environment, due to the
use of Eclipse.
SCADE System avoids duplication of efforts and inconsistencies
between system structural descriptions made of SysML Block
Definition Diagram (BDD) and Internal Block Diagram (IBD), and the
full software behavioral description designed through SCADE Suite
models. Once the system description is completed and checked, the
individual software blocks in the system can be refined in the form
of models in SCADE Suite or in the form of manually developed
source code. Automatic and DO-178B Level A-qualified code
generation can then be applied to the SCADE Suite models. Moreover,
the SCADE System description can be used as the basis to develop
scripts that will automatically integrate the complete application
software.
